The capacitor comprises a lower layer electrode 22 formed on a substrate 10 with an inter-layer insulation film 12 therebetween; an upper layer electrode 24 opposed to the lower layer electrode 22 with an inter-layer insulation film 12 therebetween, a lower interconnection layer 14 formed between the substrate 10 and the lower layer electrode 22, and electrically connected to the upper layer electrode 24, whereby the parasitic capacitance, which is a cause for lower capacitor accuracy, useless power consumption, etc. can be drastically decreased, and external noises can be shielded off.
